EDWARD C. KAHN, OF MILWAUKEE, WISCONSIN.

FLUID-FUEL BURNER,

Application filed October 2 To all whom zit may concern:

Be it known that I, EDWARD citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Fluid- Fuel Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in liquid fuel burners and is more particularly directed to the provision of an improved generator structure adapted for use preferably in connection with the type of liquid fuel burner head embodied in my previous application for patent executed November 19, 1915, and filed Oct. 27, 1916, Serial No. 128006.

One important object of the present invention is to provide a generator so formed with relation to the burner that a proper heating to rocure vaporization of the fuel is had at a l times, and wherein the danger of overheating and consequentliability of melting or otherwise injuring the generator by operation of the burner at a relatively great heat is prevented.

Another important object resides in the provision of a generator and burner head so relatively arranged and connected as to form a compact structure adapted to be supported entirely by a supply pi e member whereby the device is particular y adapted for use in connection with single head burners ofthe type including a reservoir base G. KAHN, a

member and a supplypipe stand projecting therefrom. a

A further object resides in the provision of a structure as above described wherein the parts are securely held in proper relative position for eflicient operation, and wherein all of the parts may be readily disassembled for cleaning.

It is also an object in connection with the enerator to provide a chamber wherein eposits of car on given off by vaporization of the fuel will be collected for ready removal.

With the above and other objects in view the invention resides more particularly in the novel combination, arrangement and formation of parts more particularly hereinafter descri ed and particularly pointed out in the appended claims.

} Referring now more particularly to the accompanying drawings, 5 designates the supply head which forms the body of the improved generator and burner head carrying structure, this supply head comprising a cylindrical member provided adjacent its upper end with lateral branches 6 and 7 and adapted to threadedly engage at its lower end in a supply pipe 8 which forms the support for the entire structure. This supply pipe would in some instances roject upwardly from a suitable reservoir ase (not shown) whereby the entire burner would comprise a unitary structure.

Above the branches an annular shoulder 9 is formed on the head which seats the bight of a spider member 10, the legs of which extend u wardly in divergent relation and are 0 set at their end portions to form seating led es 11 for the burner head A, this burner head being preferably of the type disclosed in my application for patent filed Oct. 27, 1916, although other of burner heads including annular series of openings could be employed. The legs 10 of the spider member are preferably V-shaped in cross-section to procure roper strength, as the spider member is pre erably stamped from a single sheet of material, and the spider member is securely held on the head 5 by a follower nut 12 threaded on the upper end of the head 5.

The generator comprises a tubular ring 13 provided at diametrically opposed portions with depending tubular sections 14 and 15 respectively which are connected each by suitable union couplings 16 to pipe sections 17 which are converged inwardly and threadedly engaged in the branches 6 and 7 respectively of the supply head whereby the generator is held spaced above the lower portion of the burner head in such relative elevation that its axial plane is disposed slightly below the plane of the lowermost series of'the jet apertures 18 of the burner head. The unions 16are preferably of a and threaded engagement with the rest sec- 60 action of the flames of the burner head ends.
